COMBINED GAGE AND STOP COCK.

Specification of Letters Patent.

Patented May 21, 1907'.

Application filed October 6,1906. Serial No. 337,665,

T0 all wwn/t 'llt T11/(ty concern:

Be it known that I, HENRY J. REYNOLDS,1 a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in a'Combined Gage and StopCock, of which the following is a specification. r

My invention relates to a combined. stop and gage cock for use uponsteam boilers and has for its object the provision of a device of thischaracter constructed in such manner that the valve and valve seat ofthe gage cock may be removed for regrinding or replacement while theboiler is under steam.

A further object of the invention is the provision of improved means fordirecting .the steam or water which issues from the gage cock in theproper direction.

Further objects and advantages of the invention will be set forth in thedetailed description which now follows.

In the accompanying drawing: Figure 1 is a longitudinal vertioalsectionof a stop and gage cock constructed in accordance with the invention,and, Fig. 2 is a transverse section upon line x of Eig. 1.

Like numerals designate corresponding parts in both of the figures ofthe drawing.

Referring to the drawing, the numeral 5 designates a valve casing whichis externally threaded as at 6, for the reception of a pack ing nut 7. Agasket 8 together with a packing nut serves to form a steam and watertight packing about a valve stem 9. A hand wheel 1() is mounted upon theouter end of this valve stem in the usual and well known manner. Thisvalve stem is threaded as at 11 into a neck 12 of the valve casing 5 andthe inner end of the valve stem is tapered to form a valve 13, thisvalve being adapted to enter a valve seat 14 located at the juncture ofthe central chamber 15 and a port 16 which leads to the boiler, notshown. The valve casing 5 is externally threaded as at 17 and it is thisportion of the valve casing that is screwed into the boiler. Threadedinto `the valve casing as at 18 and closing the lower portion of thechamber 15, is a nut 19. A valve seat 2O is formed at the upper end ofthis nut for the reception of a ball valve 21. A sleeve 22 which ispreferably formed inte gral with the nut, provides a passage for thesteam or water from the boiler as will be hereinafter described. Thebody portion of the nut is channeled as at 23 to space the sleeve fromthe walls of the nut and a second sleeve 24 receives the lower end ofthe sleeve 22 and is slidable with relation to said sleeve. Pivoted at25 to a depending portion 26 of the valve casing 5 is a lever 27. Thislever is bifurcated as at 28, the bifnrcated portions of saidleverstraddling the sleeve 24 of the depending portion 26 of the valve casing5. A pin 29 passes through the bifurcated portion of the lever, throughthe sleeve 24 and through the lower end of a plunger 30.

The operation of the device is as follows: In Fig. 1 the parts have beenillustrated in their normal position. 1f at this time the engineer orfireman lifts the outer end of the lever 27, the sleeve 24 is lifted,said sleeve sliding between the sleeve 22 and the wall of the nut 19.The plunger 30 is also lifted until its upper end contacts with theballvalve 21 and lifts said 'valve from its seat. Vater or steam as thecase may be, from the boiler, then passes through the port 16, chamber15 and sleeve 22 to sleeve 24 whence it is discharged. 1f through wearthe valve should begin to leak, the valve stem 9 may be screwed inwardby means of the hand wheel 10 until the valve 13 seats itself in thevalve seat 14, this cuts off the flow of steam or water from the boilerto the ball valve 21. By removing the pivot 25 the sleeve 24 and theplunger 30 may be pulled out of the nut 19. This nut may then beunscrewed and a new ball substituted or the valve seat 2() reground.

It will be seen that the sliding sleeve construction provides eflicientmeans for preventing the steam or water from striking upon any part ofthe structure when it is discharged.

From the foregoing description, it will be seen that simple andeflicient means are herein provided for accomplishing the objects of theinvention, but while the elements shown and described are well adaptedto serve the purposes 'for which they are intended, it is to beunderstood that the invention is not limited to the precise constructionset forth, but includes within its purview such changes as may be madewithin the scope of the appended claims.

What T claim, is:

l. In a gage cock, the combination with a valve casing adapted to bescrewed into a boiler, of a removable nut threaded into said casing,means for conducting steam or water from the boiler to said nut, saidnut having an opening formed therethrough, a valve which closes saidopening, a sleeve slidably disposed Within the nut, a valve actuatingmember disposed Within the sleeve, and a lever to Which both the sleeveand the valve actuating member are connected.

2. In a device of the character described, the combination With a valvecasing having a chamber formed therein and having a port adapted toconduct steam or Water from the boiler to said central chamber, of avalve stem threaded into said casing adapted to close said port, aremovable nut threaded into the casing and having an opening formedtherethrough, a sleeve slidably disposed in said nut, a valve Whichnormally closes the opening through said nut, a plunger adapted to liftsaid valve from its seat, and a lever to which both the plunger and thesliding sleeve are secured.

3. In a device of the character described, the combination With a valvecasing having a chamber formed therein, of a port for conducting steamor water from the boiler to said chamber, a valve stem threaded into thecasing, a valve carried by said valve stem and adapted to close saidport, a nut removably threaded into the casing and having an openingformed therethrough., a valve adapted to close said opening, a sleeveslidably disposed Within said nut, a member adapted to lift the lastnamed valve from its seat, and a lever pivoted to a member extendingfrom the valve casing, to Which both the sliding sleeve and the valveactuating member are pivotally connected.

4. In a device of the character described,

the combination with a valve casing having a chamber formed therein, ofa portfor conducting steam or Water from the boiler to said chamber, avalve stem threaded into the casing, a valve carried by said valve stemand adapted to close said port, a nut removably threaded into the casingand having an opening formed therethrough, a valve adapted to close saidopening, a sleeve slidably disposed Within said nut, a member adapted tolift the last named valve from its seat, and a Kbifurcated lever pivotedto a member extending from the valve casing, to which both the slidingsleeve and the valve actuating member are pivotally connected.

5. In a device of the character described, the combination with a valvecasing having a chamber formed therein, of a port adapted to conductsteam or Water from a boiler to said chamber, a valve stem threaded intothe casing in alinement With said port and adapted to close said port, anut threaded into the casing and having a depending sleeve, a secondsleeve slidably mounted upon said depending sleeve, a plunger mounted insaid second sleeve, a ball valve adapted to close the first namedsleeve, and a lever pivoted to a member depending from the valve casingto Which both the last named sleeve and the plunger are pivotallyconnected.

In testimony whereof I affix my signature in presence of tWo Witnesses.
